The Validate method returns a validator object, which has a number of methods that allow you to use the trigger checker or change the contents of a form **************

$.validator.setdefaults ({//Set validator Default
Debug:true,//Set debug mode to default if there is more than one form in a page this way
Errorclass: "Txt-impt",//Set CSS class name for default error prompt
Errorelement: "div"//Set default error Prompt label
})

Addmethod (Name,method,message) Method: Name (key of the Custom rules) methods (custom validation method) message (Prompt for error output)
JQuery.validator.addMethod ("Regex", function (value, element, params) {//extension Method Example:
var exp = new RegExp (params); The value of the params rules passed in the regular expression
return exp.test (value); Value that is validated by input passed in
}, "Incorrect input format");

//Extended Rules rules
JQuery.validator.addClassRules ("name", {
Required:true,
Minlength:2
});
JQuery.validator.addClassRules ({
Name: {
Required:true,
Minlength:2
},
Zip: {
Requir Ed:true,
Digits:true,
}
});
$ ("#myinput"). Rules ("Add", {
Required:true,
Minlength:2,
messages: {
Required: "Required I Nput ",
Minlength:jQuery.format (" at least {0} characters is necessary ")
}
});
$ ("#myinput"). Rules ("Remove");//Remove all validation rules
$ ("#myinput"). Rules ("Remove", "Min Max")//Remove min max

var form=$ (' form ');
$ (". Formbtn"). Click (function () {//button type non-submit or submit button not in form
Console.log ("Valid:" + form.valid ())//form.valid () Verify successful return True
var validator = $ ("form"). Validate (Setvalidate);
var formstate=validator.form (); To determine the validation status returns a Boolean
Validator.element ("ID name") verifies that an element returns a Boolean
Validator.resetform () Restores the previously validated form to its original state before verification
/*validator.showerrors ({
"FirstName": "I know that your FirstName was Pete, pete!"
}); Display custom Error Messages */

if (Formstate==false) {
Return
}else{
Do someing ...
}
})

Using AJAX to authenticate, the default is to submit the current validated value to the remote address, if you need to commit additional values, you can use the data option background only allowed to return false and True
Remote: "check-email.php"
Remote: {
URL: "check-email.php",//Background handler
Type: "POST",//Data sending method
DataType: "JSON",//Accept data format
Data: {//To be passed
Username:function () {
Return $ ("#username"). Val ();
}
}
}

Meta string Mode ***************************************************************

Introducing JS
<script type= "Text/javascript" src= "Js/jquery.metadata.js" ></script>
<script type= "Text/javascript" src= "Js/jquery.validate.js" ></script>

Validation rule notation on DOM
